Ferroptosis functions as a positive feedback amplifier downstream of heterogeneous upstream triggers (TDP-43, C9orf72, SOD1, excitotoxicity), accelerating lipid peroxidation that feeds back to worsen protein aggregation and mitochondrial damage. This makes it secondary but modifiable—explaining partial benefit from inhibitors without being curative.
**Background and Rationale** TREM2 variants represent major genetic risk factors for Alzheimer's disease, with loss-of-function mutations increasing dementia risk threefold. While TREM2 is exclusively expressed on microglia, emerging evidence suggests its primary pathogenic role occurs through disrupted astrocyte-microglia communication rather than intrinsic microglial dysfunction. Healthy brain homeostasis depends on coordinated responses between these glial populations, where TREM2+ microglia
